Which macromolecule is made of glycerol and fatty acids?

describe binomial nomenclature and its principle

Consider three genes, Aa, Bb and Cc, each of which affects a different character. The three genes are located on different chromosomes. Calculate the probability of obtaining: a) An Aa BB Cc zygote from a cross of Aa Bb Cc x Aa Bb Cc b) An Aa BB cc zygote from a cross of aa BB Cc x AA bb CC

Shila’s normal blood glucose level is 90 mg/100 ml of blood. After a meal, her blood glucose level tends to rise above normal but during fasting, her blood glucose level is low.

Describe briefly the negative feedback mechanism involved in the regulation of her blood glucose level.

A man is trapped in an air-conditioned room for 12 hours without food. Explain the physiological processes which occur.

THE MAD RUSH DOWNSTAIRS: FREE ENERGY AS THE DRIVING FORCE BEHIND CHEMICAL REACTIONS

Write out and explain the intuitive meaning of the equation for the free energy change in a chemical reaction,
and draw an accompanying color-coded and labeled graph of the equation. Talk about what drives chemical reactions
inside living cells. Be sure to carefully define all the terms in the equation, and give intuitive explanations of how changing the independent variables in the equation change the "delta G" value and thereby determine whether the
reaction goes forward, backward, or is at equilibrium. Use the hydrolysis of nucleotides in the formation of RNA
and DNA to illustrate the thermodynamic principles that allow cells to run the chemical reactions that sustain life.
At the very end, address the question of whether the chemical reactions occurring inside a living cell are at equilibrium,
or away from equilibrium, and why that has to be the case for life to go on.

Which promoter initiates which life cycle (lysogenic & Lytic)? Mention both types of promoters and their characteristics.

A group of researchers studying turtles have isolated an autosomal mutation that confers ninja-like –reflexes just prior to adulthood. This mutation is recessive to the normal slow allele (S). when homozygous slow turtle is mated to a homozygous mutant ninja turtle and the F1 are interbred, the following phenotypes are observed among the F2 young adult: 25 slow, 15 ninjas. Answer the following:

1.      What are the phenotype of the parental generation?

2.      What are the phenotype of the F1 generation?

3.      Perform the Chi-square analysis.
